Answer:
c = km
Step-by-step explanation:
Here's the required formula to find the missing side of triangle by pythagoras theorem :
- a = 20 km
- b = 21 km
- c = ?
Substituting all the given values in the formula to find the third side of triangle :
Hence, the length of missing side of triangle is 29 km.
Answer:
i'm sorry i don't understand the question. can you explain it a little bit more?
Step-by-step explanation:
5sqrt(x+7)=-10
Dividing both sides by 5:
5sqrt(x+7)/5=-10/5
sqrt(x+7)=-2
Squaring both sides of the equation:
[sqrt(x+7)]^2=(-2)^2
x+7=4
x+7-7=4-7
x=-3
Replacing in the original equation:
5sqrt(x+7)=-10
5sqrt(-3+7)=-10
5sqrt(4)=-10
5(2)=-10
10=-10 It's not equal, then x=-3 is an extraneous solution
